Thread: Timing

Does anybody know of a good way for getting system time?
i've tried timeGetTime but maybe I didn't do it right. I put the below code into the program but the numbers it outputted came out bizaar.


///////////////////////////////////////////////////////

float FrameInterval;

void CalculateSpeed()
{

static float lastTime = 0.0f;

static float frameTime = 0.0f;

float currentTime = timeGetTime();

FrameInterval = currentTime - frameTime;
frameTime = currentTime;
}

////////////////////////////////////////////////////////////

This code is actually for an OpenGL program i'm 'trying' to make which is based on Time Based Movement. I read some tutorials and the 'timeGetTime' function was the one they recommended. I posted this in this Board instead of the "Game Programming Board" because I figured it had more to do with the whole of C++.
TIA

Whoops... Sorry about above code compared to this one... I used the old code on the above example...
Heres the whole Program
///////////////////////////////////////////////////////

#include <windows.h>
#include <iostream.h>
#include <mmsystem.h>

float FrameInterval = 0.0f;

void CalculateSpeed()
{
static float frameTime = 0.0f; // This stores the last frame's time

float currentTime = timeGetTime() * 0.001f;

FrameInterval = currentTime - frameTime;
frameTime = currentTime;
}



int main()
{
for (int index = 0; index < 100000000000; index++)
{
CalculateSpeed();
cout << FrameInterval << endl;
}
return 0;
}

I get a group of numbers.... Something like
0.0076599 and repeats a couple of times
0.0076598 and repeats a couple of times
0.0076597 and repeats a couple of times
And it keeps counting down.

Is there a possibility my computer is too fast for timeGetTime?
I have a athlon2500xp @ 3200xp

Thanks
